North America interacts with the globe on a global scale, globally.

Canada:
There are quite a few wars that Canada has fought in, but not as many as its fellow North American countries. Canada was involved in the NATO bombing of Yugoslavia in 1990, as well as the Korean War. Also, the wars of 1812 and 1837 are on Canada's list. Alongside these are World Wars, the Canadian Battlefield Memorials Restoration Project, The Second Boer war, and they even played a part in the Russian Civil War
America:
  • “World’s police”
    • NAFTA, trilateral trade bloc including Canada, USA, and Mexico
America has fought in many wars, many of which we won. American Revolution was a very early war in the history of America. The War of 1812 & the Indian Wars both happened during the 1800's, the Indian wars occurring in 1817-1898. The Mexican War, the Civil War, and the Spanish-American War were finished by the turn of the century, and World War I (The Great War) kicked things off as the next big war since 1899. World War II followed soon thereafter, which was followed up by the Korean War* in 1950. The Vietnam War happened in 1975, and then the Grenada Invasion in 1983. Persian Gulf War lasted from 1990-1991. And finally comes the current war with Iraq; we are fighting for Iraqi freedom
